• 10:53 UTC (new) (history) 2021-12-11 My productivity system - design . . . . mbork – Note: this is another of those really long posts. It’s probably only interesting for some productivity geeks, since it describes my current system for beating procrastination and making most of my time (or rather, one layer of that system). In a future post I’m going to write about some (Org-mode-based) tools I use to actually implement it, but for now I just want to show the main ideas – in fact, this system was first implemented with pen and paper, and in fact it worked very well that way.

• 07:59 UTC (new) (history) 2021-12-04 Org timer once again . . . . mbork – I’ve been writing about the Org timer about a month ago, and today I’m revisiting this topic because once I started using it, I discovered a cool feature which is, let’s say, half-documented.

Sometimes the problem is that there are many edge cases, sometimes the issue is conceptually hard, and sometimes both. Recently, I had an instance of a problem which was conceptually hard (at least for my little brain).

• 04:44 UTC (new) (history) 2021-11-13 y-or-n-p but with RET meaning yes . . . . mbork – Today, I had an extremely specific need. I wanted the Elisp function y-or-n-p (which asks the user a yes-or-no question, expecting a one-key answer of y or n), but I wanted to interpret RET (or “Enter”) as “yes”. It turns out that by default it means “exit”, which is because y-or-n-p-map has no binding for RET, and y-or-n-p falls back on query-replace-map (in a rather convoluted way). So, here is one way I could change it:
